8 Claims. 1

This invention relates to a, device for winding up webbing from looms onwhich it is woven. The loom may Weave a number of these webs, forexample of the order of an inch or an inch and a half wide,simultaneously. given merely as examples, as other Widths may be woven.Normally each web is wound u on a roll or block, all mounted on a commonshaft which is driven by the loom mechanism. However, to take off anycoil it is necessary to take off a shaft section with all the rolls, andthen each coil of webbing is loosenedso it may be slid from the reel, orit is rewound'onto another reel. It is an object of my device to permittaking off any one or more of the reels of wound webbing desired,without unwinding the web, and disturbing a minimum number of the otherreels, thus providing accelerated operation of the loom and the windingdevice, and greatly reducing the time the loom is not operating due toremoving the wound coils and mounting the blocks.

With the foregoing and other objects in view, I have devised theconstruction illustrated inthe accompanying drawings forming a part ofthis specification. It is, however, to be understood the invention isnot limited to the specific details of construction and arrangementshown, but may embody various changes and modifications within the scopeof the invention.

The wind-up device Ill provides a suitable means for winding up thestrips of webbing H which are woven by the loom, the front end portionof which is represented diagrammatically by 12, Fig. 1. The wind-updevice 10 comprises a series of collapsible reels or blocks 13 mountedon a shaft 14 made in sections and driven from each end by the drivemechanism 15, which may be any of the usual drive means for the wind-upreels or beams, such as a ratchet or like driven from the loom mechanismby the rods 15a. Two sets of four reels or blocks each are shown in Fig.1, the two shaft sections 25 and 28 supporting these reels being carriedin two end bearings 16 and I1 and an intermediate bearing I8. Thesenumbers are shown merely by way of example, as the number of reels in aset may be varied as desired and the number of shaft sections may alsobe as found desirable.

The bearing 16 is an ordinary bearing, while the bearings l1 and I8 areopen on one side, as at l9 (Figs. 2, 8 and 9) so that the shaft [4, ormore specifically the individual shaft sections, may be removed by.sliding it out of the bearing through this opening |9.- The shaft 14 isheld in the bearings l1 and I8 by the pivoted clips 20 and 21 providedwith finger grips 22 and pivoted at 23 at opposite ends of the bearingsl1 and I8 so that they may be swung upwardly as at 2|, Figs. 8 and 9,-torelease the shaft, or may be swung down as at 20, Figs. 8 and 9, to holdthe shaft in place.

The shaft i4 is made in sections, which permits removal from thebearings l1 and [8 of onesec tion without disturbing the other sections.In the form of the device shown in Fig. 1, the shaft H is in foursections, 24, 25, 28 and 2'1, with four winding reels or blocks 13 oneach of the two central sections'25 and 26. However, it is to beunderstood that as many sections as desired may be used, with one ormore winding reels l3 at tached thereto.

Theleft end section 24 in the bearing 16 has an. enlarged head 28 with asocket 253 in it to receive the notched end of the shaft 25, the notchbeing a transverse groove 30 which when seated in the socket 2B,embraces the transverse pin 31 mounted in the enlarged head '28 andextending across thesoc'ket 311, so that as the shaft section 24 isrotated by the drive mechanism 15 it will rotate the shaft section 25'.However, it is clear that the shaft section 25 may be withdrawn withoutdisturbing the shaft section 24.

The shaft section 25 extends to the intermeaeidco vided with a similartransverse rib 32, as shownin Fig. 4, to fit a transverse groove, thesame as 33, in the right hand shaft section 21, which is driven by theright hand drive Hi.

The shaft section 25 carries a plurality of collapsible reels or blocksIS on which the webbing H is wound and similarly the shaft sec tion 25carries a similar series of collapsible reels [3. The collapsible reelcomprises two head members or end blocks 34 and 35 mounted on therotatable shaft section 25 or 26. Between the two end blocks 34 and 35is the winding drum 36, which consists of two semicylindrical sectionsseparated as at 31, Fig. 11. On the inside of each of these sections ofthe drum 36 is secured by a suitable means, such as welding or screws(not shown) a channel shaped member 38, located longitudinally of thedrum 36.

At the end of each channel and between its parallel sides, levers 39 arepivoted by means of pivot pins 40, the levers 39 also being pivoted bypivot pins 4| between lugs 42 on the end blocks 34 and 35, thus securingthe drum 36 to the end blocks 34 and 35. The reel i3 is located at anydesirable position on the shaft 25 or 26, by means of a locating collar43, held on the shaft 25 or 26' by aset screw 44, which permits thecollar to be shifted longitudinally of the shaft to any desiredlocation. The end block 34 is placed against the collar 43, andseparated from it by a wearing washing 45 composed of fibre or othersuitable material. A coil spring 46 embracing the shaft 25 or 25 isplaced between the end blocks 34 and 35 so that it tends to push the endblocks 34 and 35 away from each other. Now, however, if the end block 35is shifted toward the end block 34, the pivots 4| will move toward eachother, causing the pivots 45 to move outwardly, and in this manner thedrum moves to the expanded position, the sections separating, as shownby dotted lines at 31, Fig. 11. The drum is held in this position bymeans of a movable collar 48 against the head 35 which is knurled toprovide a convenient gripping means, and which is heldin position by aset screw 48a. It is while the drum 36 is in this position that thewebbing H is wound on it, the drum being driven by the rotating shaft 25or 26 through a. friction drive in the end block 34, which consists of aleather plug 52 or other suitable material held against the shaft withany desirable pressure by means of a set screw 50. It is clear that thisfriction drive enables the shaft 35 to rotate at a greater speed thanthe drum 36, thus keeping tension on the webbing at all times as itcomes from the loom. If desired, the surfaces of the drum sections 36may be covered with emery'cloth or similar roughened surface material 53to increase its grip on the web being wound.

When the desired amount of webbing has been wound onto the drum 36, setscrew 48a in the collar 38 is loosened and the collar moved to theright, or away from the collar 43. The coil spring 46 then spreadstheend blocks 34 and 35 by shifting block 35 to the right. In thismanner the pivots 3! move away from each other, causing the levers 29 tocontract the drum 36 to the position shown by solid lines, Fig. 11. Lugs5| on the levers l9 provide a limiting means to prevent the end blocksfrom being spread farther than desired. When the drum 36 is thuscontracted the roll of webbing may be easily removed from the drumwithout unwinding the webbing, by simply slidin the webbinglongitudinally off the drum.

Thus it is clear that with this arrangement all the wound up webbing onthe reels [3 at the left of the bearing l8 may be removed withoutdisturbing those at the right hand of this bearing IS, in the followingmanner: by merel lifting the pivoted clip 23 on the bearing E8, theright hand end of the shaft section 25 may be slid out of the bearing l8through its open side l9, as shown in Figs. 2, 8 and 9. If the shaft isturned so that the rib 32 is positioned as shown, with one end facingthe open side I 9 of the bearing, it may be slid out without disturbingthe shaft section 26. Then the left hand end of the shaft section 25 maybe withdrawn from'the socket 29 of the left end shaft section 24, andthe various coils of webbing removed by collapsing their respectivewinding drums, or if preferred, the winding drums 36 may be collapsedwhile the shaft section is still in position, and the coils of Webbingmerely slid off the collapsed drums and then off the right hand end ofthe shaft 25 which has been shifted forwardly out of the bearing l8.Similarly, the other section 26 of the shaft, together with its windingdrums l3 and the coils of webbing, may be inserted or removedindependently of the shaft section 25, and the coils of webbing may beremoved in the same manner. It is therefore not necessary to remove thewhole shaft to remove the reels or coils or webbing or any particularreel or coil. Also, the shaft sections can be removed individuallywithout dismounting the bearings or disassembling them. c
